Covid mu variant - Mu COVID Variant, Which Sparked Fears Over Vaccine Resistance, Eradicated in U.S.
Auparavant considéré comme « variant d'intérêt », Thêta a été déclassé par l'OMS début juillet 2021.
Singh said these past two years have been difficult but sees it as his civic duty to support the community through scientific research.
The vanishing COVID variants: Lessons from gamma, iota and mu
Without these efforts, it is unlikely this vaccine would be available for several years, if at all.
How do vaccines work against this variant? The vaccines, however, help to halt the spread of the virus, thereby hindering its ability to mutate — so do masks and other layers of prevention, such as keeping a safe distance from others and avoiding crowds and poorly ventilated indoor settings.
Au sein du RBM, trois segments contiennent des reconnus par les anticorps : la crête receptor-binding ridge - RBR localisée aux codons 417, 455-456 et 470—490, et deux boucles loop localisées aux codons 443-452 L1 et 494-501 L2.
The Mu variant, also known as lineage B.1.621 or VUI-21JUL-1, is one of the variants of SARS-CoV-2, the virus that causes COVID-19. It was first detected in Colombia in January 2021 and was designated by the WHO as a variant of interest on August 30, 2021.
The mu variant’s sequencing indicates it has features that could still make it infectious to people who have either natural immunity due to a previous COVID-19 infection or acquired immunity due to vaccination.
Mu may be the dominant variant in Colombia, but Fauci has said it’s “not at all even close to being dominant,” in the U.S. And “there are a lot of factors that would have to happen for that to be the case,” Durbin adds. “These viruses are sort of in a fight to the finish. The fittest virus is the one that survives,” she says.
Mu is the fifth variant of interest to be monitored by the WHO since March. It has a number of mutations that suggest it could be more resistant to vaccines, the health agency warned, but stressed that further research would be needed to confirm this. Preliminary data show a reduced effectiveness of vaccines “similar to that seen for the Beta.
